摘　　要：石油污染土壤对生态环境和人体健康具有重大危害,物理、生物和化学修复技术是处理石油污染土壤常用的方法,但石油污染物在土壤中的吸附却限制了修复效果;表面活性剂对吸附于土壤中的疏水性有机污染物的解吸和迁移具有很好地促进作用,在石油污染土壤修复中发挥着越来越重要的作用。本文介绍了物理、生物和化学修复技术的研究现状和优缺点;阐述了表面活性剂的分类和作用机理,综述了表面活性剂与电动修复、生物修复和化学氧化修复联合应用的研究进展,简要介绍了应用表面活性剂的限制因素和环境风险。Petroleum-contaminated soil is a major hazard to the ecological environment and human health.Physical,biological and chemical remediation techniques are commonly used to treat petroleum-contaminated soil,but the effect of remediation is limited by the adsorption of petroleum pollutants in the soil.Surfactants can promote the desorption and migration of hydrophobic organic pollutants adsorbed in soil and play an increasingly important role in the remediation of petroleum contaminated soil.This paper introduced the current research status,advantages and disadvantages of physical,biological and chemical remediation as technologies.The classification and mechanism of action of surfactants were described.The research progress on the joint application of surfactant with electroremediation,bioremediation and chemical oxidative remediation was reviewed.The limiting factors and environmental risks of the application of surfactants were briefly introduced.
